Title: Time-varying flow estimation for virtual flow metering applications
Inventor: Valentin Thomas
IPC: E21B43/12
Filed: 2017-10-09
Abstract: Virtual flow estimation is described that is suitable for use under steady-state and non-steady-state (i.e., transient) conditions. Examples of such an approach may not perform discretization of the underlying model described by partial differential equations, but may instead perform discretization in a derived estimator separate and distinct from the underlying model. In this manner, a non-executable continuous time-estimator may be transformed to an executable discrete time-estimator suitable for use in under non-steady state (i.e., transient) conditions.

Title: Diversity receiver front end system with flexible band routing
Inventor: WILLIAM J DOMINO
IPC: H04B7/08
Filed: 2015-10-28
Abstract: The invention relates to a multi-band receiver comprising an input demultiplexer 311 connected to an output multiplexer 712 through a plurality of paths. Each path includes a respective amplifier 314a-314d and each path may pass a respective band of a plurality of bands. The output multiplexer has two outputs 735a, 735b, each connected to a respective transmission line. When a controller receives a band select signal indicating multiple frequency bands are to be received and the controller is aware that one of the transmission lines is unusable, the controller controls the multiplexer to combine received signals from multiple different frequency bands and route the combined signal to the other transmission line. The unusable transmission line may be unusable due to damage, or merely because it is not present in a particular wireless communication configuration. The receiver may form part of a diversity receiver.
